Apple iPhone 5 new A6 chip clocked at 1.30GHz

Apple iPhone 5 new A6 chip clocked at 1.30GHz

There's no doubting that the A6 processor inside the iPhone 5 is a fast chip. The dual-core ARM v7 combined with a triple-core GPU puts it well ahead of the iPhone 4S. However, what wasn't totally clear was how fast the A6 is running inside the phone.
Initially, Geekbench tests pegged the A6 at 1.02GHz, which was a small bump over the 800MHz A5 inside the iPhone 4S. The speed increase accounted for the improved performance of the smartphone if you also consider that new GPU and the optimizations included with iOS 6. But the iPhone 5 is really fast and more than doubles the Geekbench results of the 4S is the majority of Geekbench tests. Surely something else was pushing those results up?
An update to the Geekbench app (v2.3.6) has revealed that initial speed of 1.02GHz was a little bit low. Running the latest version pegs the A6 at 1.3GHz. At first it was thought this could be a sign of dynamic overclocking with the A6 upping the speed to cope with the tasks being thrown at it. But now it seems more likely the initial speed estimate was wrong and better hardware detection in Geekbench has revealed the true speed.
If you run the latest version of the Geekbench app on your own handset you will likely see something around that speed, with both 1.29GHz and 1.3GHz being seen so far. If the iPhone 5 does have dynamic overclocking no one has proved it yet, but if an even higher clock speed is reported, it could still be a feature of the phone yet to be revealed properly.
